Monel pipe application: The nuclear industry for the manufacture of uranium isotope separation and refining equipment, water power plant in the seamless pipe, steam pipe, water exchanger and evaporator, sulfuric acid and hydrochloric acid, crude distillation equipment used in seawater pump shaft and propeller. Monel K500 (K500, NCu30-2-1, UNS, N05500) alloy has high strength, corrosion resistance, non magnetism and excellent mechanical properties, but also has the same corrosion resistance with Monel 400. The utility model can be used as a pump shaft material and is suitable for mining under the conditions of poor high sulfur and high wax oil layer. Since the alloy has no plastic brittle transition temperature, it is very suitable for various cryogenic equipment. This alloy is mainly used for pump shaft and valve stem, conveyor scraper, oil well drilling ring, elastic parts, valve pad and so on. It is suitable for petroleum, chemical, shipbuilding, pharmaceutical and electronic sectors.

Monel 400 alloy (UNS N04400 or MCu-28-1.5-1.8 or Ni68Cu28Fe) is a kind of nickel based alloy material, which has good resistance to corrosion in water, ammonia, sulfur and chlorine, hydrogen chloride, various acid media such as sulfuric acid, hydrofluoric acid, hydrochloric acid, phosphoric acid, organic acid, alkaline, salt and molten salt.

Monel 400 alloy has good mechanical properties, good welding performance, high strength. Monel 400 is mainly used in chemical and petrochemical industry and marine development and other fields. It can be used to make all kinds of heat exchange equipment, boiler feed water heater, oil and chemical pipelines, containers, towers, tanks, valves, pumps, reactors, shafts and so on. Executive Standards: ASTM B 164 (rod, line), ASTM B 564 (forging), ASTM B 127 (plate, band), ASTM B 165 (seamless tube).
